One of my more obscure hobbies listening to shortwave radio, especially the amateur's or "hams". It's all SSB and worth listening to for news tidbits.
`
I used to enjoy tracking meteors live as they enter the earth's atmosphere. Used a TV receiver set to the frequency of a distant TV transmitting tower, fed the output to an audio in jack on a computer and then through a FFT (Fast Fourier Transform) program that displayed the data as a "waterfall" display. The idea being that the ionized trail of the meteor would reflect the line-of-sight video signal back down to the earth. An incoming meteor would show up as a streak across the waterfall display.
And then there was the time I tried to build an x-ray machine... my high voltage supply was an Oudin coil that, as I learned from the FCC people who knocked on my parents' door, was wiping out TV reception in the area. That's when I learned about well-grounded Faraday shielding.
So, no, shortwave listening is so unusual!
